Is the cost per project output breakout mandatory? Can we choose to leave this out or only provide costs per goal?

Costs per project output are scored under our evaluation criteria and therefore should be included.  

We also recognize that not everything is known at the time of proposal development; please just do the best you can in estimating costs and scheduled completion dates over the three-year period of performance (as this is the length of project your workplan should reflect). You can easily update these dates through your semi-annual reporting, or more substantial changes can be made through change requests (in which you would just send a revised workplan to your Regional Exchange Network Coordinator).
